Letters Patent No. 111,396, dated January 31, 187i.

IMPROVEMENT IN BENCH-VISES FOR WOOD-WORK.

The Schedule referred to in these Letters Patent and part of the same.

To all '1v/wm 'it may concern Be it known that I, EDWIN SPRAGUE, ofthecity and county of Allegheny and State of Pennsylvania, have inventeda new and useful Improvement in Bench-Visas for Icod-Work, &c.; and I dohereby declare. that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters oi' reference marked thereon.

v The nature of my invention consists in a bench-vise having theclamping-jaws pivoted to a support which may be secured to a bench orother` place, the 'clamping-jaws and support being:T so arranged withrelation to each other as to form a high-and-iow vise, the

Figure 2 is avertical section of the same, cut through at line y of tig.1.

In the accompanying drawingx represents a bench or table, to which isattached a support, x', into which is iii-ted. the attachment-plate D,which is secured in support x' by means of screws or bolts.

vIn the attachment-plate I) is fitted the flange of the nut C, which issecured to the damping-jaw B by means of screws or bolts. Y

The ange of the nut O is fitted in the opening of the attachmennplate Dso as to form a dovetail and pivot-joint, as shown in Iig. 2.

"lhe damping-jaw A is operated by the screw e,

which is of ordinary construction, and worlis in the nut C.

rIhe screw c is turned and manipulated by means of the lever h. 4

The lower end of the `clamping-jaw is held in the desired position withrelation to lthe clampingiaw B by means of the ordinary steady-bar i.

T0 the lower end of the support cv', and to the leaf or top ofthe benchz, is secured a sector;v g, to which is ttcd a tightening-screw, f,which is itted in the lower end ot' the clamping-jaw B.

By means of this tightening-screw f, sector g, and pivoting theclamping-jaw Bin the manner hereinbev fore described, the vise can beset at any desired an# gle, and the vertical plane of the clamping-jawscan be 'arranged parallel to the horizontal plane of the leaf or top ofthe bench x, inA which position the entire length of the clamping-jaws Aand B may be used for griping or holding any article placed betweenthem, the advantage of which will be apparent to carpenters,pattern-makers, cabinet -makers, and other wood-working mechanics. v L

By constructing a vise as hereinbefore described, a high-and-low vise isobtained, with the advantages oa narrow and broad grip of the jaws, andalso the advantage of setting the clamping-jaws at any desired angle.

Having thus described the nature, construction, and operation of myimprovement,

What I claim as of my invention is- The clamping-jaw B, provided with anut or box, O, attachment-plate D, and'combined with the clampingjaw A,and screw c, substantially as herein described.
